Here are Jain-friendly boy names starting with “Bh” that you can consider. I’ve kept them simple and noted any strong Jain association.

• Bhadrabahu — name of a revered Jain sage and monk; the tradition often uses this as a given name to honor his spiritual stature.
• Bhavya — means noble or splendid; commonly used in Jain and broader Indian naming.
• Bhadrak — a compact form that inherits the auspicious flavor of “bhadra.”
• Bhadranath — combines “bhadra” (auspicious) with “nath” (lord/guardian); used in Indian naming traditions, including among Jain communities.
• Bhavendra — a variant that conveys a sense of nobility and brightness.
• Bhargava — a traditional name used across Indian communities; occasionally found in Jain contexts as well.

If you’d like, tell me any preferences (traditional vs. modern, religious significance, length, etc.) and I’ll tailor a tighter list.
